Each reader reads only what is already within himself. The book is only a sort of optical instrument which the writer offers to the reader to enable the latter to discover in himself what he would not have found but for the aid of the book.

Love is space and time measured by the heart.

The true voyage of discovery is not a journey to a new place; it is learning to see with new eyes.

We have such numerous interests in our lives that it is not uncommon, on a single occasion, for the foundations of a happiness that does not yet exist to be laid down alongside the intensification of a grief from which we are still suffering.

The one thing more difficult than following a regime is keeping from imposing it on others.

Griefs, at the moment when they change into ideas, lose some of their power to injure our heart.

Pleasures are like photographs: in the presence of the person we love, we take only negatives, which we develop later, at home, when we have at our disposal once more our inner dark room, the door of which it is strictly forbidden to open while others are present.
